Same issue here.
iwconfig reports some number and it doesn't change no matter how the real rate
varies depending on signal (I guess it's stuck on some initial rate).
while "iw dev wlan0 link" reports the rate properly and matches the rate I see
on the router's end.
I've run this a few times and I can see "iw" reporting the rate changes
while "iwconfig" is stuck at the same number all the time.
$ iwconfig wlan0 | grep Rate
Bit Rate=144.4 Mb/s Tx-Power=15 dBm
$ iw dev wlan0 link | grep rate
tx bitrate: 300.0 MBit/s MCS 15 40Mhz short GI
$ iwconfig wlan0 | grep Rate ; iw dev wlan0 link | grep rate
Bit Rate=144.4 Mb/s Tx-Power=15 dBm
tx bitrate: 150.0 MBit/s MCS 7 40Mhz short GI
$ iwconfig wlan0 | grep Rate ; iw dev wlan0 link | grep rate
Bit Rate=144.4 Mb/s Tx-Power=15 dBm
